Primary Outcome Measures :
  1. Time to re-initiation of cART during analytical treatment interruption (ATI) [ Time Frame: Up to 26 weeks. ]
    Time from date of cART cessation to the date of the last of three consecutive plasma HIV-1 RNA measurements >10,000 copies/mL, CD4 cell count <350 on two consecutive measurements, or end of ATI (i.e. 26 weeks after cessation of cART) - whichever comes first.


Secondary Outcome Measures :
  1. Safety and Tolerability assessment measured by AEs, Adverse Reactions (ARs), SAEs, [ Time Frame: Duration of the study ]
    Subject who receives at least one dose of the IMP(s) will be included in the evaluation for safety, measured by AEs, Adverse Reactions (ARs), SAEs, Serious ARs (SARs) and (SUSAR)

  2. Plasma HIV RNA doubling time [ Time Frame: Duration of ATI (up to 26 weeks) ]
    Plasma HIV RNA doubling time from first measurement >50 copies/mL to first measurement >1,000 copies/mL during the analytical treatment interruption (plasma HIV RNA measured by standard clinical assays, e.g. Cobas TaqMan; Lower limit of quantitation 20 copies/mL)

Criteria

Inclusion Criteria:

  • Documented HIV-1 infection
  • Adults age 18-65 years
  • On ART for a minimum of 18 months.
  • CD4+ T cell count >500 at screening
  • HIV-1 RNA plasma level of < 50 copies/mL by standard assays for at least 15 months (a single viral load measurement > 50 but < 500 copies/mL during this time period is allowable).
  • Able to give informed consent
  • Viral reservoir sensitivity to 3BNC117 and 10-1074. (Sensitivity of the viral reservoir to neutralization by 3BNC117 and 10-1074 will be tested following the screening visit (i.e. prior to randomization)).

Exclusion Criteria:

  • Any significant acute medical illness requiring hospitalization in the past 4 weeks
  • Any evidence of an active AIDS-defining opportunistic infection
  • Any condition that, in the Investigator's opinion, will prevent adequate compliance with study therapy
  • The following laboratory values at screening, the values can be repeated within the screening period, but test results must be available before baseline (Day 0) and checked for eligibility: Hepatic transaminases (AST or ALT) ≥3 x upper limit of normal (ULN) // Serum total bilirubin ≥3 ULN // Estimated glomerular filtration rate (eGFR) ≤50 mL/min (based on serum creatinine) // Platelet count ≤100 x109/L // Absolute neutrophil count ≤1x109/L
  • Hepatitis B or C infection
  • History of: Malignancy, excluding non-melanoma skin cancers, or organ transplantation
  • Receipt of strong immunosuppressive or systemic chemotherapeutic agents within 28 days prior to study entry
  • Known resistance to >2 classes of ART
  • Known hypersensitivity to the components of lefitolimod, 3BNC117, 10-1074 or their analogues
  • Pre-existing autoimmune or antibody-mediated diseases
  • Women who are pregnant or breastfeeding, or unwilling/ unable to use an acceptable method of contraception (if of child bearing potential)
  • Males or females who are unwilling or unable to use barrier contraception during sexual intercourse until plasma HIV-1 RNA is undetectable using standard assays
